Abstract

To provide a steam turbine rotor and a steam turbine which are highly reliable.
The steam turbine rotor is characterized in that a forged material B having a hollow structure is joined to a forged material A of a Ni group super-alloy by welding, and weld back waves on an inner surface are removed, and the inner surface is smoothed, and a forging material C and a forging material B are joined to each other with a bolt.
